How do we live with and use bats that makes viruses crossing over more likely, though?
> Of 23 samples that came from Wuhan, only three were type A, the rest were type B, a version two mutations from A. But in other parts of China, Forster says, initially A was the predominant strain. For instance, of nine genome samples in Guangdong, some 600 miles south of Wuhan, five were A types.

Where else would you research ebola?
No matter how hard you yell it, correlation is not causation (and even when there is causation, the direction of the causation isn't always obvious).

(Marburg virus is a variant of Ebola)
Indirectly via animals like minks/civits being farmed. The bats can occasionally infect those animals, when those zoonotic jumps happen there's then a large bioractor of animals in close contact, resulting in a "serial gain of function" experiment to produce a virus which is adapted to those animals and can spread.
Every factory farm is a stochastic virus research laboratory that isn't even BSL-1 trained.
